In January 2016 SPIE sent email survey invitations to a large subset of its global customer database. Response was voluntary and open. An iPad rafﬂe and early access to this report were offered as incentives to encourage participation. Surveys were completed online using SurveyGizmo’s enterprise survey tool. Results were filtered to yield 6,793 valid responses. Responses from employed respondents lacking salary data were removed, as were duplicates and responses from retirees. Microsoft Excel and SPSS were utilized to create summary statistics and related disaggregations.
